b9cc16a5e8 kernel: Set CONFIG_RCU_CPU_STALL_TIMEOUT=21
The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.

This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

505b7a2d08 kernel: move two symbols to the generic kconfigs
CONFIG_RCU_{NEED_SEGCBLIST,STALL_COMMON} are set basically everywhere. Move them
to the generic kconfigs. And resort the generic kconfigs while at it.

7e135add24 kernel: disable CONFIG_RCU_EXPERT and friends
Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.

Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

c18f91d118 kernel: Do not deactivate staging drivers
Do not deactivate the kernel configuration symbol CONFIG_STAGING in the
target configurations any more. This prevented the build of the exfat.ko
for example.

27b5bae2ec treewide: remove redundant ubifs kconfig symbols
For the targets which enable ubifs, these symbols are already part of the
generic kconfigs. Drop them from the target kconfigs.

ccf65613da kernel: add disabled PROC_STRIPPED
Otherwise the missing symbol is added to target config for every kernel
config refresh.

While at it, remove the disabled symbol from target configs.

9ba09653ad treewide: remove maintainer variable from targets
There is no such role as target maintainer anymore, one should always
send corresponding changes for the review and anyone from the commiters
is allowed to merge them or eventually use the hand break and NACK them.

Lets make it clear, that it is solely a community doing the maintenance
tasks.
